Contributing to this exciting piece of work from the @graeffjohannes.bsky.social lab was a fun ride. We show that partial reprogramming restricted to engram neurons suffices to counteract behavioural, molecular and cellular signs of aging and Alzheimer's. Check it out: www.cell.com/neuron/fullt...

Auschwitz Memorial @auschwitzmemorial.bsky.social · 27/01/2026
Auschwitz was at the end of a process. We must remember that it did not start from gas chambers. This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder. Auschwitz took time.

Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Venezuela hoy da la imagen del mundo que traen las fuerzas reaccionarias: agresiones militares ilegales, la razón de la fuerza bruta, el capricho imperial como norma. Un mundo de siervos en el que nadie esté a salvo.

🚨The paper from my postdoc in @graeffjohannes.bsky.social’s lab at @epfl-brainmind.bsky.social is out! We show that memories can be switched on and off by simply changing the « packaging » of DNA in neurons through epigenetic editing. www.nature.com/articles/s41...

CRISPR-based epigenetic editing is used in a cell-type-specific, locus-restricted and temporally controllable manner in the adult mouse brain to modulate memory expression.

The whole point of democracy is so one person's derangement does not become everybody's problem. It's social hygiene. The fact the richest men in the West are a mix of grotty twelve year olds and deranged apocalypse fanatics is a problem, and we should be honest about it.

I think a lot about what Carl Sagan said in one of his final interviews.
"WE'VE ARRANGED A society based on science and technology, in which nobody understands anything about science technology. And this combustible mixture of ignorance and power, sooner or later, is going to blow up in our faces. Who is running the science and technology in a democracy if the people don't know anything about it?"
"Science is more than a body of knowledge, it's a way of thinking. A way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along."

Extraordinary scenes in Serbia’s capital Belgrade right now. Around 500,000 people are on the streets in what may be the biggest protest in Serbian history. All demanding the resignation of President Vučić & his government. What began as a student protest is now a full democratic uprising. 🇷🇸
